Table 1 - Number of application cases approved by the WA

To streamline the process, enhanced measures have been introduced. They include regulation of the submission arrangement and formulation of a submission check list for plumbing proposals. For more details about the application process, please refer to the Guide to Application for Water Supply.

Plumbing works must NOT commence until the plumbing proposal has been approved by the WA in writing. The licensed plumber (LP) is required to submit Form WWO 46 Pt. I & II together with a duly completed Form WWO 1149 (List of Pipes and Fittings intended to be Installed) to apply for the permission of the Water Authority to proceed with the works under the approved plumbing proposal. (For applications with Form WWO 1149 already approved with the plumbing proposal, only Form WWO 46 Part I & II is required.)

Table 2 - Number of permissions to commence plumbing works by the WA

To facilitate preparation of the submissions, a webpage is dedicated to helping applicants to search and select the pipes and fittings with valid General Acceptance (GA) and directly convert to the format of the required Form WWO1149, which can be downloaded for printing and signing, for subsequent submission to the WA. For more details, please see Circular Letter No. 3/2017.

Form WWO46 Pt.III will be issued to the applicant when the proposal submitted is generally acceptable.

Upon completion of the plumbing works, the licensed plumber is required to notify the WA immediately using Form WWO 46 Pt. IV.

Table 3 - Number of completed plumbing works approved by WA

To enhance the inspection process of plumbing works and to shorten the time for completing the inspection process of cases in interim and final inspection, a "Scheme on Voluntary Submission of Inspection Checklist" was launched for the licensed plumbers (LPs) to join on a voluntary basis. Under the scheme, LPs are required to carry out an inspection on completed plumbing works and complete the respective inspection checklist for interim and/or final inspection. The completed checklist has to be certified by qualified registered professionals. Audit checks will be carried out by WSD on items of the checklist inspected by the LP and certified by qualified registered professionals. In addition, WSD would conduct checks on items not inspected by the LP on a random basis. For more details, please see Circular Letter No. 1/2018.
